## Long description

The DeLOCK RF/EMI interference suppression filter is a D‑Sub adapter with a 25‑pin male to 25‑pin female connection that integrates low‑pass broadband filters to reduce radio frequency and electromagnetic interference. It is intended for use on D‑Sub interfaces to stabilise signal transmission on serial ports (for example RS‑232 and RS‑485) as well as digital and analogue I/O lines. The connectors are brass with gold plating on contact surfaces and the adapter is available in blue and silver finishes.
Advantages
The adapter incorporates 25 low‑pass broadband filters to provide RF/EMI shielding directly at the D‑Sub interface, helping to prevent interruptions and signal noise. The in‑line design preserves pin compatibility while adding filtering, and the plated brass contacts improve durability and electrical conductivity.
Suitable for
Serial RS‑232 and RS‑485 connections
Digital I/O interfaces where EMI suppression is required
Analogue I/O lines sensitive to RF noise
Applications requiring a 25‑pin D‑Sub male to female adapter
Key specifications
Connector 1: D‑Sub 25 pin (male)
Connector 2: D‑Sub 25 pin (female)
Filter type: Low‑pass broadband, 25 integrated filters
Use: RF/EMI interference suppression for D‑Sub interfaces
Contact plating: Brass with gold plating on contacts
Available colours: Blue, Silver
Brand: DELOCK, MPN: 66549, EAN: 4043619665495
How to use
Connect the male D‑Sub 25 pin side of the adapter to the corresponding female port on your device and attach the female side to the cable or mating connector. Ensure proper mechanical fastening of the D‑Sub screws to maintain a reliable contact. The integrated low‑pass filters operate passively and require no configuration or power; they function once the adapter is installed in the signal path.
Usage recommendations
Use this adapter where D‑Sub signal stability is important and RF/EMI interference is present or suspected. Verify pinout compatibility before installation and avoid exposing the adapter to excessive mechanical stress or corrosive environments to maintain contact integrity.
